What crops are sown in winter?

There are not many crops growing in winter. Apart from greenhouse crops, there are few open-air crops, such as wheat, rape and peas. In addition, some fruit trees in the orchard can also be counted.

Different crops will have certain differences in the focus of winter cold protection. The following little helpers will talk to you separately.

1, wheat

In winter, winter wheat is protected against cold by pouring frozen water, which increases the ground temperature and ensures the safe winter of wheat. However, when pouring frozen water, it is not recommended to drown it with water. If there is water in the field for a long time, it may lead to frostbite.

In addition, if it is a prosperous wheat field, it should be controlled in time to improve the width of wheat straw and the growth ability of root system. At the same time, for wheat fields with weak and yellow seedlings, a part of urea can be properly applied to improve the resistance of wheat itself and ensure safe overwintering.

2. Rape

Attention should be paid to the vigorous growth of rape during overwintering, and paclobutrazol should be sprayed to control the vigorous growth and increase the frost resistance of rape plants themselves. At the same time, it can also be irrigated in winter. Just like wheat, we shouldn't drown it with water. It is advisable to irrigate all the fields today, so as to ensure that there is no water in the fields for a long time. If possible, we can also apply some fertilizer after irrigation.

3. Greenhouse crops

For greenhouse crops, the most important thing is to prevent freezing, whether it is vegetables, fruits or flowers. Before winter, we should pay attention to check the greenhouse to ensure its tightness. In case of snowfall, we can cover it with straw curtains in advance. In addition, the greenhouse should be ventilated regularly to ensure the safe growth of greenhouse crops. Finally, if there is heavy snowfall in the local area, we should pay attention to the snow removal work above the greenhouse to avoid its collapse.

4. Orchard

Orchard management, before winter, for fruit trees that can be pruned, it is necessary to prune them properly in time, especially some diseased branches. In addition, winter is a good time to clean up the orchard, do a good job of cleaning up, destroy the wintering sites of pests and diseases, and reduce the occurrence of pests and diseases. Finally, if the local temperature is low, you can spread grass properly in the orchard, which will play a certain role in resisting the cold of fruit trees.

At present, the time has reached 65438+mid-February, the temperature is getting lower and lower, and the snowfall range is gradually increasing. It is hoped that farmers will do a good job in the management of winter crops to ensure safe wintering.

Finally, let me ask you a question: What wintering crops have you planted this year?
